The QFocusEvent class contains event parameters for widget focus events.
Focus events are sent to widgets when the keyboard input focus changes. Focus events occur due to mouse actions, keypresses (e.g. Tab or Backtab), the window system, popup menus, keyboard shortcuts or other application specific reasons. The reason for a particular focus event is returned by reason() in the appropriate event handler.
The event handlers QWidget::focusInEvent() and QWidget::focusOutEvent() receive focus events.
Use setReason() to set the reason for all focus events, and resetReason() to set the reason for all focus events to the reason in force before the last setReason() call.
| enum QFocusEvent::Reason |
This enum specifies why the focus changed.
Mouse because of a mouse action. Tab because of a Tab press. Backtab because of a Backtab press (possibly including Shift/Control, e.g. Shift+Tab). ActiveWindow because the window system made this window (in)active. Popup because the application opened/closed a popup that grabbed/released focus. Shortcut because of a keyboard shortcut. Other any other reason, usually application-specific.
See the keyboard focus overview for more about focus.
| enum QFocusEvent::Reason |
| QFocusEvent::QFocusEvent | ( | Type | type | ) | [inline] |
Constructs a focus event object.
The type parameter must be either QEvent::FocusIn or QEvent::FocusOut.
| QFocusEvent::QFocusEvent | ( | Type | type | ) | [inline] |
| bool QFocusEvent::gotFocus | ( | ) | const [inline] |
Returns TRUE if the widget received the text input focus; otherwise returns FALSE.
| bool QFocusEvent::gotFocus | ( | ) | const [inline] |
| bool QFocusEvent::lostFocus | ( | ) | const [inline] |
Returns TRUE if the widget lost the text input focus; otherwise returns FALSE.
| bool QFocusEvent::lostFocus | ( | ) | const [inline] |
| static Reason QFocusEvent::reason | ( | ) | [static] |
| QFocusEvent::Reason QFocusEvent::reason | ( | ) | [static] |
Returns the reason for this focus event.
| void QFocusEvent::resetReason | ( | ) | [static] |
Resets the reason for all future focus events to the value before the last setReason() call.
| static void QFocusEvent::resetReason | ( | ) | [static] |
| void QFocusEvent::setReason | ( | Reason | reason | ) | [static] |
Sets the reason for all future focus events to reason.
| static void QFocusEvent::setReason | ( | Reason | reason | ) | [static] |
